Augmented reality as an aid for the use of machine tools
TypeArticles dans des revues avec comité de lecture
This article presents a work in progress of using augmented reality as a way to help handling computer numerical control (cnc) machine tools. Several reasons justify the use of augmented reality in machine tools: (i) a high complexity of using such machines, especially for beginners; (ii) low ergonomics since the operator has to move continuously between the machine window and a control screen to ensure smooth operations; (iii) the window is often obstructed by the lubricant, therefore the operator must often rely only on information displayed by the control screen; (iv) a non-user-friendly interface of the machine; and (v) a complex maintenance operation. In this work, a prototype of a system allowing an operator to improve its working conditions and better handle cnc machines using ar devices is proposed. These devices are positioned in front of the machine, connect to it and display real-time information, such as the operating conditions and a 3d representation of the cutting tool motion. A user interface was also designed to manage operators’ profiles with customized information. The system was tested by several users who confirmed its potentialities to assist machine operators in their work. Other possibilities of this system are under investigation, such as a training tool for beginners and a guide for machine maintenance.

Influence of cutting process mechanics on surface integrity and electrochemical behavior of OFHC copper DENGUIR, Lamice; OUTEIRO, José; FROMENTIN, Guillaume; VIGNAL, Vincent; BESNARD, Rémy (ELSEVIER, 2014)Superfinishing machining has a particular impact on cutting mechanics, surface integrity and local electrochemical behavior. In fact, material removal during this process induces geometrical, mechanical and micro-structural ...
Orthogonal cutting simulation of OFHC copper using a new constitutive model considering the state of stress and the microstructure effects DENGUIR, Lamice; OUTEIRO, José; FROMENTIN, Guillaume; VIGNAL, Vincent; BESNARD, Rémy (Elsevier, 2016)This work aims to develop an orthogonal cutting model for surface integrity prediction, which incorporates a new constitutive model of Oxygen Free High Conductivity (OFHC) copper. It accounts for the effects of the state ...
DENGUIR, Lamice; OUTEIRO, José; FROMENTIN, Guillaume; VIGNAL, Vincent; BESNARD, Rémy (Elsevier, 2017)Due to the rising interest in predicting machined surface integrity and sustainability, various models for metal cutting simulation have been developed. However, their accuracy depends deeply on the physical description ...
